1 A Fresh Look at the Mainframe Consolidate and Save with Mainframe Linux ODI is Wasting Money! Your last report showed an average utilization of less than 5% for our distributed Linux servers isn t that wasteful? If we consolidate on our IBM mainframe, we can save lots of money through virtualization! On Demand Insurance CEO On Demand Insurance CIO 09 - Consolidate and Save with Mainframe Linux v3.0..ppt 2 1

2 UNIX and Windows Server Utilization Typical Examples App Server, Prod, PL6400R 4-way, Win2K Exchange, Prod, PL 6400R 1-way, Win2K Avg. utilization 4.5% (during day shift) Avg. utilization 4.8% (during day shift) App Server, Sun E way, Solaris Avg. utilization 18% (during day shift) Mainframes Aggregate Daytime Utilization % Unix Servers Aggregate Daytime Utilization 15-20% Windows Servers Aggregate Daytime Utilization < 5% 09 - Consolidate and Save with Mainframe Linux v3.0..ppt 3 Sprawling Server Farms Are Also Costly To Manage A Financial Services Company 68 Windows support staff at $100K/year, fully burdened 16 servers per person $6,000 per year per server for labor Another Financial Services Organization 7 Windows support staff at $125K/year fully burdened rate 19 servers per person $6,500 per year per server for labor Source: IBM Scorpion Customer Studies 09 - Consolidate and Save with Mainframe Linux v3.0..ppt 4 2

3 Why Does Server Sprawl Happen? Applications cannot run together Distributed server architecture strongly favors single application deployment Low level hardware architecture affects performance & integrity Need to isolate applications from intrusive software maintenance (reboot!) Many sets of servers required per application Production, Development, Testing, Disaster/recovery, Training, Support New versions require new stacks, often leading to new server-sets Deployed by different lines of business using private resources Ease and speed of acquisition and deployment Little concern for standardization Centralization is perceived as slow, inflexible & expensive Politically difficult to centralize important line of business resources 09 - Consolidate and Save with Mainframe Linux v3.0..ppt 5 Theoretically Run the Same Workloads with Less Resources Workload 1 Workload 2 Workload 3 Workload 4 Workload 5 Servers needed Servers needed Servers needed Servers needed Servers needed WL 1 WL 4 WL 2 Peak usage pool WL 3 WL 5 What s Required: Virtualization and Intelligent Workload Management to Accommodate Shifting Workloads automatic on the mainframe! 09 - Consolidate and Save with Mainframe Linux v3.0..ppt 6 3

4 Mainframe Supports Virtualization and Workload Management Virtualization is where the available resources remain pooled Each OS sees a truly virtual machine As workload demands, real resources are dynamically allocated Enables massive over-commitment of real resources Works well for real-life, mixed business workloads Works significantly better on mainframe hardware Mainframe architecture is shared-everything, distributed is not Extremely fine granularity in memory, CPU, I/O bandwidth etc Consolidate and Save with Mainframe Linux v3.0..ppt 7 Consolidate Linux Workloads onto System z to Save Money 5% utilization 95% utilization of fewer processors All of the qualities of services of the System z platform 09 - Consolidate and Save with Mainframe Linux v3.0..ppt 8 4
